BACKGROUND

Electronic spreadsheets are often used in the retrieval, manipulation and/or display of data.

For example, electronic spreadsheets are often used to retrieve data from a database, to perform one or more computations using the data, and/or to display the data and/or the results of the computations. The database from which the data is retrieved is sometimes part of a processing system, such as for example an enterprise resource planning (ERP) system, or a business intelligence (BI) system, both provided by SAP AG headquartered in Walldorf, Germany.

More space is sometimes needed to display data in a portion of a spreadsheet. In some instances, a neighboring portion of the electronic spreadsheet may be overwritten to provide the needed space. In other instances, additional rows and/or columns may be added to the electronic spreadsheet in order to provide the needed space.

For example, data 182 may be stored in the database and the user device 122 may communicate with the database 112, directly and/or indirectly, to request the data 182 from the database 112. In some embodiments, one or more of the user devices 122-126 communicates with the server 114 to request the data from the database 112.

FIGS. 2A-2F are representations of views in a user interface that illustrate a method for use in association with an electronic spreadsheet application program, in accordance with some embodiments.

As further described below, in some embodiments, items in an electronic spreadsheet are associated with positions in a stack and may overlap one or more portions of one another without resulting in complete overwriting (i.e., deletion) of such portions.

In some embodiments, one or more of the views and/or one or more portions of the method may be provided in association with an electronic spreadsheet application program executed by a processor within one or more user devices, e.g., one or more of the user devices 122-126.

The method (or portion(s) thereof) may be performed using hardware, software (which may include low level language code and/or high language code) and/or any combination thereof. For that matter, any of the methods (or portion(s) thereof) described herein may be performed using hardware, software (which may include low level language code and/or high language code) or any combination thereof. In some embodiments, a storage medium may store thereon instructions that when executed by a machine result in performance of one or more portions of the method.

Notably, the views and the method disclosed herein are not limited to the views and method represented in FIGS. 2A-2F. Rather, other embodiments may use any views and method that is practicable.

Referring to FIG. 2A, a view 200 in a user interface for an electronic spreadsheet application program includes an electronic spreadsheet 202 and a toolbar 204 surrounded by a border 206.

The electronic spreadsheet 202 includes a plurality of cells arranged in an array having a plurality of rows, e.g., represented by rows 1-25, and a plurality of columns, e.g., represented by columns “A”-“J”. The electronic spreadsheet 202 further includes a top border 208, which includes identifiers for the plurality of columns, e.g., A-J, and a side border 210, which includes identifiers for the plurality of rows, e.g., 1-25. In some embodiments, each of the plurality of cells in the spreadsheet 202 may be empty, or alternatively, it may contain a numerical value, a formula or one or more alphanumeric characters. A given cell may be referred to herein by the column and the row in which the given cell is located. Thus, the cell in column A and row 1 may be referred to herein as cell A1, the cell in column A and row 2 may be referred to herein as cell A2, the cell in column A and row 3 may be referred to herein as cell A3, and so on.

The toolbar 204 may include a plurality of graphical tools, e.g., buttons represented by the words “FILE”, “EDIT”, VIEW”, and “INSERT”, each of which may be activated by a user to access a respective drop down menu associated therewith. For example, the “INSERT” button may be activated to access a pull down menu 212 associated with the “INSERT” button. In some embodiments, the pull down menu 212 may include a plurality of graphical tools, e.g., which may include a button 214 represented by the word “ITEM”. The button represented by the word “ITEM” and/or some other type of graphical tool in the view 200 may be activated to access a graphical tool, e.g., a dialogue box, that may be used to add an item to the electronic spreadsheet 202. The dialogue box 216 or other graphical tool to add an item may include a graphical tool 217, e.g., a check box, to indicate that the item should be a blank item or template (e.g., blank item or template 218) and/or a graphical tool, e.g., a button 219, to indicate that the item is an existing item and to request an opportunity to browse for the existing item. In some embodiments, one or more items may be added by opening a document that defines one or more items, e.g., by activating the “FILE” button and an “OPEN” button in a drop down menu associated therewith.

The view 200 may further include one or more other graphical tools (not shown).

The border 206 defines a top edge, a bottom edge and side edges of the view 200.

Referring to FIG. 2B, in a view 220, a first item 221 has been added to the electronic spreadsheet 202. The first item 221 represents a set of data that is usable in populating a plurality of the cells (e.g., inserting a numerical value, a formula or one or more alphanumeric characters into each of the plurality of cells) in the electronic spreadsheet 202. In some embodiments, the first item represents a set of multidimensional data that is stored in, and/or retrieved from, one or more databases, e.g., database 112 of processing system 102. In some embodiments, data may be retrieved from the one or more databases by querying the one or more databases.

The first item 221 may have any form.

In the illustrated embodiment, the first item 221 includes a table having a plurality of rows 222-244 and a plurality of columns 252-258. The first two rows 222-224 of the table are header rows that include a plurality of identifiers (e.g., “REGION CODE”, “NET SALES-PLAN”, “NET SALES” and “SALES”), each of which is associated with a respective one of the plurality of columns 252-258 and indicates the type of information that is listed in the respective one of the plurality of columns 252-258. For example, the identifier “REGION CODE” is associated with a first column 252 and indicates that region code dimension members (e.g., “ATLANTA”, “CENTRAL”, “CHICAGO”, “MONTREAL”, “NORTH EAST”, “SOUTHEAST”, “TORONTO”, “WEST” AND “NOT ASSIGNED”) are listed in the first column 252. A dimension member “OVERALL RESULT” represents an aggregate of the other region code dimension members. The “OVERALL RESULT” dimension member is shown in the third row 256, which is above the other region code dimension members. However, in some embodiments, the “OVERALL RESULT” dimension member is in a row that is below, rather than above, the other region code dimension members. The identifier “NET SALES” is associated with a third column 256 and indicates that net sales measures are listed in the third column 256. The identifier “SALES PLAN” is associated with a fourth column 258 and indicates that sales plan measures are listed in the fourth column 258. The identifier “NET SALES-PLAN” is associated with a second column 254 and indicates that the second column 254 lists differences that are computed based on two measures, i.e., a net sales measure and a sales plan measure.

The third row 226 indicates an overall result for a sales plan measure.

Each of the other rows, i.e., rows 228-242, defines a line entry that is associated with a respective one of the region code dimension members listed in the first column 252. For example, row 228 is a line entry that is associated with the dimension member “ATLANTA”. It includes a net sales measure (0.61*1000) for the dimension member “ATLANTA”, a sales plan measure (none) for the dimension member “ATLANTA”, and difference (610.00) between the net sales measure for the dimension member “ATLANTA” and the sales plan measure for the dimension member “ATLANTA. And so on.

A symbol, e.g., “+”, adjacent to a dimension member in the first column 252 indicates that the table can be expanded to show additional dimension members associated with that dimension member. A graphical tool, e.g., a button represented by the “+” symbol adjacent to the dimension member in the first column 252, may be activated to request that such additional dimension members be added to the table. In some embodiments, the additional dimension members associated with the dimension member are hierarchically arranged with respect to the dimension member. For example, these additional dimension members may be decedents of the dimension member. In some embodiments, the request to add additional dimension members may result in additional rows (in the table) that include the additional dimension members. In some embodiments, the additional rows are directly below the row that includes the dimension member associated with the additional dimension members, e.g., as illustrated in FIG. 2E.

Referring to FIG. 2C, in a view 260, a second item 261 has been added to the electronic spreadsheet 202. As with the first item 221, the second item 261 represents a set of data that is usable in populating a plurality of the cells in the electronic spreadsheet 202. In some embodiments, the second item 261 represents a set of multidimensional data that is stored in, and/or retrieved from, one or more databases, e.g., database 112 of processing system 102.

The second item 261 may have any form.

In the illustrated embodiment, the second item 261 includes a table having a plurality of rows 262-269 and a plurality of columns 272-274. The first two rows 262-264 of the table are header rows that include a plurality of identifiers (e.g., “PRODUCT GROUP” and “BILLED QUANTITY”), each of which is associated with a respective one of the plurality of columns 272-274 and indicates the type of information that is listed in the respective one of the plurality of columns 272-274. For example, the identifier “PRODUCT GROUP” is associated with a first column 272 and indicates that product group dimension members (e.g., “ACCESSORIES”, “BAG&OUTDOOR” and “OFFICE”) are listed in the first column 272. The identifier “BILLED QUANTITY” is associated with a second column 274 and indicates that billed quantity measures are listed in the second column 274.

The third row 266 indicates an overall result for a billed quantity measure.

Each of the other rows, i.e., rows 267-269, defines a line entry that is associated with a respective one of the product group dimension members listed in the first column 272. For example, row 267 is a line entry that is associated with the dimension member “ACCESSORIES”. It includes a billed quantity measure (820,857.004) for the dimension member “ACCESSORIES”. And so on.

A symbol, e.g., “+”, adjacent to a dimension member in the first column 272 indicates that the table can be expanded to show additional dimension members associated with that dimension member. A graphical tool, e.g., a button represented by the “+” symbol adjacent to the dimension member in the first column 272, may be activated to request that such additional dimension members be added to the table.

Referring to FIG. 2D, in a view 280, a third item 281 has been added to the electronic spreadsheet 202. As with the first item 221 and the second item 261, the third item 281 represents a set of data that is usable in populating a plurality of the cells in the electronic spreadsheet 202. In some embodiments, the third item 281 represents a set of multidimensional data that is stored in, and/or retrieved from, one or more databases, e.g., database 112 of processing system 102.

The third item 281 may have any form.

In the illustrated embodiment, the third item 281 includes a table having a plurality of rows 282-284 and a plurality of columns 285-291. The first two columns 285-286 of the table include a plurality of identifiers (e.g., “CUSTOMER” and “BILLED QUANTITY”), each of which is associated with a respective one of the plurality of rows 282, 284 and indicates the type of information that is listed in the respective one of the plurality of rows. For example, the identifier “CUSTOMER” is associated with a first row 282 and indicates that customer dimension members (e.g., “AUTO”, “CHURCH”, “HEAVY IND” and “NOT ASSIGNED”) are listed in the first row 282. The identifier “BILLED QUANTITY” is associated with the row 284 and indicates that billed quantity measures are listed in the third row 284.

The third column 287 indicates an overall result for a billed quantity measure.

Each of the other columns, i.e., columns 288-291, defines a line entry that is associated with a respective one of the customer dimension members listed in the first row 282. For example, column 288 is a line entry that is associated with the dimension member “AUTO”. It includes a billed quantity measure (1,186.187) for the dimension member “AUTO”. And so on.

A symbol, e.g., “+”, adjacent to a dimension member in the first row 282 indicates that the table can be expanded to show additional dimension members associated with that dimension member. A graphical tool, e.g., a button represented by the “+” symbol adjacent to the dimension member in the first row 282, may be activated to request that such additional dimension members be added to the table. In some embodiments, the request to add additional dimension members may result in additional columns (in the table) that include the additional dimension members. In some embodiments, the additional columns are directly to the side of the column that includes the dimension member associated with the additional dimension members.

Each item is associated with a respective location in the electronic spreadsheet. In the illustrated embodiment, the first item 221 is associated with a first location in the electronic spreadsheet, e.g., cell B3 to cell E14 (sometimes indicated as B3:E14). The second item 261 is associated with a second location in the electronic spreadsheet, e.g., cell C19 to cell D24 (sometimes indicated as C19:D24). The third item 281 is associated with a third location in the electronic spreadsheet, e.g., cell D16 to cell J18 (sometimes indicated as D16:J18).

Each item is also associated with a respective position (or priority) in a stack. In the illustrated embodiment, a default convention is to associate the first item 221 with a maximum position (or priority) in the stack, to associate the second item 261 with a next highest position (or priority) in the stack and to associate the third item 281 with a next highest position (or priority) in the stack. However, other default conventions may also be used.

In some embodiments, the stack position represents a priority in a view. A highest priority in the stack may be treated as being in front of all other priorities in the stack. A second highest priority in the stack may be treated as being behind the highest priority in the stack but in front of all priorities other than the highest priority in the stack. And so on.

In the illustrated embodiment, none of the items 221, 261, 281 overlaps (i.e., located at a position that corresponds with the position of) another item, in whole or in part. In such embodiment, each item may be used in populating the plurality of cells of the electronic spreadsheet that are overlapped by (i.e., located at positions that correspond with the position of) such item. Thus, the first item 221 is used in populating cells B3:E14. For example, the first column is used in populating cells B3:B14 (where a first entry in the first column is used in populating cell B3, the second entry in the first column is used in populating cell B4, the third entry in the first column is used in populating cell B5, and so on), the second column is used in populating cells C3:C14, the third column is used in populating cells D3:D14, and so on. The second item 261 is used in populating cells C19:D24. The third item 281 is used in populating cells D16:J18.

However, as further described below, in some embodiments, one or more of the items may be moved and or expanded, and as a result, the location of such item may overlap the location of one or more of the other items.

As further described below, in some embodiments, the stack positions (or priorities) may be used to determine which items will be used to populate certain cells of the electronic spreadsheet in the event that the location of one or more of the items in the electronic spreadsheet overlaps the location of one or more other items in the electronic spreadsheet.

It should be understood that a stack may be explicitly implemented, e.g., as described herein, and/or implicit implemented.

It should also be understood that in some embodiments, the items need not overlap one another, in whole or in part.

Referring to FIG. 2E, in a view 292, a first item 221 has been expanded, e.g., by activating a graphical tool (e.g., the button represented by the “+” symbol adjacent to the dimension member “CENTRAL” in the first column 252). The first column 252 now also includes second dimension members (e.g., distribution channel dimension members “EDI”, “FAX”, INTERNET”, “OTHERS” and “PHONE”) that are associated with the first dimension member “CENTRAL”. Moreover, table now includes additional rows 293-297, each of which defines a line entry that is associated with a respective one of the second dimension members (e.g., distribution channel dimension members “EDI”, “FAX”, INTERNET”, “OTHERS” and “PHONE”) that are associated with the first dimension member “CENTRAL”. For example, row 293 is a line entry that is associated with the second dimension member “EDI”. It includes a net sales measure for the second dimension member “EDI”, a sales plan measure (none) for the dimension member “EDI”, and difference between the net sales measure for the dimension member “EDI” and the sales plan measure for the dimension member “EDI. And so on.

Notably, the first item 221 is now associated with a spreadsheet location of B3:E19 which overlaps the spreadsheet location of the second item 261 and the spreadsheet location of the third item 281.

The electronic spreadsheet 202, or at least a portion thereof, is rendered in accordance with the information defining the plurality of items, the respective location associated with each item and the respective stack position associated with each item.

Because the first item 221 has the highest stack position (or priority), the data of the first item 221 is used to populate each of the plurality of cells of the electronic spreadsheet that are overlapped by (i.e., located at positions that correspond with the position of) the first item 221.

As a result, a portion of the second item 261 and a portion of the third item 281 are no longer visible in the view 292.

However, such portion of the second item 261 and such portion of the third item 281 may be retained by the electronic spreadsheet application program and may remain available to populate cells of the electronic spreadsheet in the event that the relative stack positions (or priority) of the first item 221, the second item 261 and/or the third item 281 are changed (and/or in the event that the relative locations of the first item 221, the second item 261 and/or the third item 281 are changed).

Referring to FIG. 2F, in a view 298, a stack position of the third item 281 has been changed, such that the third item 281 now has the maximum stack position (or priority) and the stack positions of the first item and the second item 281 have been adjusted accordingly.

Because the third item 281 now has the maximum stack position (or priority), the data of the third item 281 is used to populate each of the cells overlapped by (i.e., located at positions that correspond with the position of) the third item 281.

As a result, a portion of the first item 221 and a portion of the second item 261 are no longer visible in the view 298.

However, such portion of the first item 221 and such portion of the second item 261 may be retained by the electronic spreadsheet application program and may remain available to populate cells of the electronic spreadsheet in the event that the relative stack positions (or priority) of the first item 221, the second item 261 and/or the third item 281 are changed (and/or in the event that the relative locations of the first item 221, the second item 261 and/or the third item 281 are changed).

In the illustrated embodiment, a graphical tool, e.g., a button represented by the words “BRING TO FRONT”, in a menu 299, may be activated to request that the stack position of the third item 281 (or any other item) be set equal to the maximum stack position (or priority).

In some embodiments, a menu 299 for changing a stack position of the third item 281 (or other item for which the respective stack position is to be changed) is accessed by positioning a mouse cursor 299A onto the third item 281 (or other item for which the respective stack position is to be changed) and by pressing a right mouse button while maintaining such positioning of the mouse cursor.

In the illustrated embodiment, the menu 299 may also be used to request other changes to the stack position of the third item 281 (or any other item)

For example, a button represented by the words “SEND TO BACK”, may be activated to request that the stack position of the third item 281 (or any other item) be set equal to the minimum stack position (or priority). A button represented by the words “BRING FORWARD”, may be activated to request that the stack position (or priority) of the third item 281 (or any other item) be incremented by 1. A button represented by the words “SEND BACKWARD”, may be activated to request that the stack position (or priority) of the third item 281 (or any other item) be decremented by 1.

In some embodiments, changing the stack position of the first item 221, such that the first item 221 again has the maximum stack position (or priority) and adjusting the stack positions of the second item 261 and the third item 281 accordingly, may result in the view 292 of FIG. 2E.

Dragging may comprise positioning a mouse cursor 510 onto the representation associated with an item for which the respective stack position is to be changed, e.g., the third item 281, by pressing a left mouse button and then moving the mouse to a desired position while maintaining the pressing of the mouse button.

Referring to FIG. 5C, after the change is requested, the representations may be arranged in a new sequence that is in accordance with the requested change. For example, the third representation 506 may be positioned first in the sequence because it is associated with the third item 281, which after the change is associated with the highest stack position (or priority). The first representation 502 may be positioned second in the sequence because it is associated with the first item 221, which after the change is associated with the second highest stack position (or priority). The second representation 504 may be positioned third in the sequence because it is associated with the second item 261, which after the change is associated with the third highest stack position (or priority).
